Implantation or Period?

I hate to be so disgusting with everyone, but I'm desperate to know. Yesterday I had light bleeding that started out light pink/brown. It was on and off throughout the evening. I started to get some cramping last night and woke up to more blood this morning, but not like yesterday's. The cramping isn't as bad like I usually have. My period has started out brown a few times before then progressed, same with my mom.  What do you all think?
